Array() displaying in all pages of admin -view page source

It might be added during development, most probably coming from Theme or Plugin, The best way to debug is download active plugins and active theme using this plugin Download Plugin/ Theme, and open code in VSCode and search for var_dump, var_export, print_r, die, and etc.

I’d say first search in Theme than go for Plugins.
